Ntuziaka ndị dị ugbu a na mmepụta ihe mkpuchi ihe mkpuchi XLPE gụnyere ihe mkpuchi ọkụ ọkụ ọkụ ọkụ ọkụ ọkụ PE, ihe mkpuchi ikuku ikuku PE, na ihe mkpuchi ọkụ ọkụ na-ekpuchi ọkụ na-ekpuchi ihe mkpuchi polyolefin.
(2)Ihe mkpuchi ihe mkpuchi polypropylene (XL-PP) jikọtara ya:
Polypropylene (PP), dị ka plastik a na-ahụkarị, nwere njirimara dị ka ịdị arọ dị arọ, nnukwu ihe onwunwe akụrụngwa, ọnụ ahịa na-akwụ ụgwọ, ezigbo nguzogide corrosion kemịkalụ, ịdị mfe nke ịkpụzi, na imegharị ihe. Otú ọ dị, ọ nwere njedebe dị ka ike dị ala, nkwụsị ọkụ na-adịghị mma, nrụrụ dị ịrịba ama nke ịda mbà n'obi, nkwụsị nke na-adịghị mma, obere okpomọkụ na-ekpo ọkụ, na adịghị ike na-eguzogide okpomọkụ na ikuku oxygen. Mmachi ndị a amachibidola iji ya na ngwa eriri. Ndị na-eme nchọpụta na-arụ ọrụ iji gbanwee ihe polypropylene iji meziwanye ọrụ ha n'ozuzu ya, na irradiation cross-linked modified polypropylene (XL-PP) emeriwo njedebe ndị a nke ọma.
Waya mkpuchi mkpuchi XL-PP nwere ike izute ule ọkụ ọkụ UL VW-1 yana ụkpụrụ waya 150ºC nwere ọkwa UL. Na ngwa eriri bara uru, a na-ejikọta EVA na PE, PVC, PP, na ihe ndị ọzọ iji dozie arụmọrụ nke mkpuchi mkpuchi eriri.
Otu n'ime ọghọm nke irradiation cross-linked PP bụ na ọ na-agụnye mmeghachi omume asọmpi n'etiti nhazi nke njedebe na-adịghị mma site na mmeghachi omume nbibi na mmeghachi omume njikọ n'etiti ụmụ irighiri ihe na-akpali akpali na nnukwu radicals free molecule. Nnyocha e mere egosiwo na nha nke mmebi na mmeghachi omume na-ejikọta na PP irradiation cross-linking bụ ihe dịka 0.8 mgbe ị na-eji irradiation gamma-ray. Iji nweta mmeghachi omume njikọ njikọ dị irè na PP, ọ dị mkpa ka agbakwunye ndị na-akwalite njikọ njikọ maka irradiation cross-linking. Na mgbakwunye, ọkpụrụkpụ njikọ njikọ dị mma na-ejedebe site na ike ntinye nke ihie elektrọn n'oge irradiation. Irradiation na-eduga na mmepụta nke gas na ụfụfụ, nke bara uru maka ijikọta ngwaahịa ndị dị mkpa ma na-egbochi iji eriri ndị nwere mgbidi.

Ka ọchịchọ maka nchekwa eriri na-abawanye, mmepe nke eriri ọkụ na-egbochi ọkụ na-enweghị halogen etoola ngwa ngwa. E jiri ya tụnyere PE, EVA, nke na-ewebata monomers vinyl acetate n'ime agbụ molecular, nwere obere crystallinity, na-ebute mgbanwe mgbanwe dị mma, nguzogide mmetụta, ndakọrịta ihe na-ekpo ọkụ, na ihe mkpuchi ọkụ. N'ozuzu, njirimara nke resin EVA na-adabere na ọdịnaya nke vinyl acetate monomers n'ime agbụ molekụla. Ọdịnaya vinyl acetate dị elu na-eduga n'ịbawanye nghọta, mgbanwe, na ike. EVA resin nwere ezigbo ndakọrịta njupụta na njikọ njikọ, na-eme ka ọ na-ewu ewu na eriri ọkụ na-egbochi ọkụ halogen na-enweghị njikọ.
A na-ejikarị resin EVA nwere vinyl acetate dị ihe dịka 12% ruo 24% na mkpuchi waya na eriri USB. N'ime ngwa USB n'ezie, a na-ejikọta EVA na PE, PVC, PP, na ihe ndị ọzọ iji dozie arụmọrụ nke mkpuchi mkpuchi eriri. Akụkụ EVA nwere ike ịkwalite njikọ njikọ, na-eme ka arụmọrụ USB dịkwuo mma mgbe ị na-ejikọta ya.
(4) Ihe mkpuchi Ethylene-Propylene-Diene Monomer (XL-EPDM) jikọtara Cross-Linked:
XL-EPDM bụ terpolymer nke ethylene, propylene, na diene monomers na-abụghị conjugated, jikọtara ya site na irradiation. XL-EPDM cables na-ejikọta uru nke eriri polyolefin na-ekpuchi ọkụ na eriri ndị na-ekpuchi roba:
1. Mgbanwe mgbanwe, nkwụghachi azụ, enweghị nkwụsị na okpomọkụ dị elu, ogologo oge ịka nká, na iguzogide ihu igwe siri ike (-60 ° C ruo 125 ° C).
2. Ozone eguzogide, UV mgbochi, eletriki mkpuchi arụmọrụ, na iguzogide chemical corrosion.
3. Nguzogide mmanụ na ihe mgbaze na-atụnyere ihe mkpuchi mkpuchi chloroprene n'ozuzu. Enwere ike ịmepụta ya site na iji ngwá ọrụ nhazi ọkụ na-ekpo ọkụ na-emekarị, na-eme ka ọ bụrụ ọnụ ahịa.
XL-EPDM eriri mkpuchi mkpuchi nwere ọtụtụ ngwa dị iche iche, gụnyere ma ọnweghị oke na eriri ọkụ eletrik dị ala, eriri ụgbọ mmiri, eriri mgbanye ụgbọ ala, eriri njikwa maka compressors refrigeration, eriri mkpanaka igwe na-egwuputa ihe, akụrụngwa akụrụngwa, na ngwaọrụ ahụike.

(5) Ihe mkpuchi mkpuchi silicone
rọba silicone nwere mgbanwe na ezigbo nguzogide ozone, mwepu corona na ọkụ, na-eme ka ọ bụrụ ihe dị mma maka mkpuchi ọkụ. Ngwa ya bụ isi na ụlọ ọrụ eletrik bụ maka wires na eriri. Silicone rubber wires na cables na-adabara nke ọma maka ojiji na gburugburu okpomọkụ na nke na-achọsi ike, na-enwe ogologo ndụ ogologo oge ma e jiri ya tụnyere eriri ọkọlọtọ. Ngwa ndị a na-ahụkarị gụnyere moto okpomọkụ dị elu, ndị na-agbanwe agbanwe, ndị na-emepụta ọkụ, ngwa eletrọnịkị na eletriki, eriri mgbanye n'ime ụgbọ njem, yana eriri mmiri na njikwa.
Ka ọ dị ugbu a, a na-ejikọta eriri silicone rọba mkpuchi mkpuchi site na iji ikuku ikuku nwere ikuku dị ọkụ ma ọ bụ uzuoku dị elu. A na-eme nyocha na-aga n'ihu na iji electron beam irradiation maka roba silicone na-ejikọta ọnụ, n'agbanyeghị na ọ kabeghị ebe niile na ụlọ ọrụ USB. Site na ọganihu na-adịbeghị anya na teknụzụ na-ejikọta irradiation cross-linking, ọ na-enye ọnụahịa dị ala, dị mma na gburugburu ebe obibi maka ihe mkpuchi mkpuchi silicone. Site na irradiation eletrọn ma ọ bụ isi mmalite radieshon ndị ọzọ, enwere ike nweta njikọta nke ọma nke mkpuchi mkpuchi silicone ma na-enye ohere ịchịkwa omimi na ogo nke njikọ njikọ iji zute ngwa achọrọ.
N'ihi ya, ngwa nke irradiation cross-linking technology maka silicone roba mkpuchi ihe na-ekwe nkwa dị ịrịba ama na waya na cable ụlọ ọrụ. A na-atụ anya na teknụzụ a ga-ebelata ọnụ ahịa mmepụta, melite arụmọrụ mmepụta, ma tinye aka n'ibelata mmetụta gburugburu ebe obibi ọjọọ. Mgbalị nyocha na mmepe n'ọdịnihu nwere ike ime ka ojiji nke teknụzụ na-ejikọta irradiation maka ihe mkpuchi rọba silicone, na-eme ka ha bụrụ ndị a na-ejikarị eme ihe maka ịmepụta okpomọkụ dị elu, wires na-arụ ọrụ dị elu na eriri eletrik na ụlọ ọrụ eletrik. Nke a ga-enye ihe ngwọta a pụrụ ịdabere na ya na nke na-adịgide adịgide maka mpaghara ngwa dị iche iche.
